"Mental rotation tasks (see this CogDaily post), which require working with a three-dimensional representation of an object, have been found to have very large sex differences favoring males"
Thanks for the citation. That same article says that "at least one study has found that it's possible to teach these visuospatial skills." I can interpret the result "males in the study did better at mental rotation tasks" to mean "males brains are wired better" or "males have better math educations". Both interpretations fit the study evidence as presented.
The 3rd part of the linked article even says:
"So it appears that there are a wide variety of social factors that affect (or are affected by) sex differences in math and science. Because of limitations in the way these studies can be controlled, it's difficult to say that discrimination or differential treatment cause the sex differences we see in math and science."
Overall, the linked articles do not support the hypothesis that "men's brains are wired better".
